![]() ![]() Glenn Llewellyn, Airbus VP of Zero-Emission Aircraftīecause fuel cells generate electricity through an electrochemical reaction, they are a clean source of power. This partnership will be a phenomenal acceleration in bringing hydrogen fuel cells to future aircraft. Today, Airbus has significant know-how in electric propulsion and fuel cells thanks to work carried out at our E-Aircraft System House and currently taking place at the ZAL in Hamburg. In the cathode, the protons and oxygen then combine to produce water.Ī PEM, Proton Exchange Membrane cell uses hydrogen gas and oxygen gas as fuel.The negatively charged electrons flow out of the cell and generate an electric current, which can be used, for example, to power an electric or hybrid-electric propulsion system. The positively charged protons pass through the porous electrolyte membrane to the cathode.Oxygen from the ambient air enters on the other side through the cathode. Here, hydrogen atoms react with a catalyst and split into electrons and protons. ![]() Hydrogen enters the fuel cell via the anode.Composed of two electrodes (an anode and a cathode) separated by an electrolyte membrane, a typical hydrogen fuel cell works in the following way: Similar to batteries, a fuel cell is a device that converts energy stored in molecules into electricity through an electrochemical reaction. Tomorrow, it could potentially power everything from low-carbon cities and regions to portable computing devices to future zero-emission aircraft. power a variety of transportation modes such as cars, buses, trains and forklifts.replace grid electricity for critical-load facilities like data centres.provide emergency backup power to critical facilities like hospitals.Today, hydrogen fuel cell technology is being used for a variety of applications, including to: As the story goes, then-US President Richard Nixon famously said: "Without you Tom, we wouldn't have gotten to the moon.” It remained a scientific curiosity until the 20th century, when English engineer Francis Thomas Bacon matured the original idea to develop the world’s very first hydrogen-oxygen fuel cell in 1932.īacon’s fuel cell was such a success that it has been used by the space industry to power satellites and rockets for space exploration programmes, including Apollo 11, since the 1960s. At the time, he called his invention a “gas voltaic battery.” Unfortunately, it did not produce enough electricity to be of much use. In 1838, judge-turned-scientist Sir William Grove came up with a novel idea: to construct a cell consisting of two separate sealed compartments, each of which was fed by either hydrogen or oxygen gas. In a strategic partnership with automotive systems supplier ElringKlinger, Airbus is investing to mature fuel cell propulsion systems for the aviation market. This means you only need about half the amount of hydrogen, with double the fuel economy.H ydrogen fuel cells are emerging as a high-potential technology that offers significant energy efficiency and decarbonisation benefits to a range of industries-including automotive and heavy transport. But because a fuel cell is more than twice as efficient as an internal combustion engine, a fuel cell car travels farther on that tank of hydrogen than a traditional car would on gasoline. Since the “engine” (i.e., fuel cell) has no moving parts, you’ll never need to change the oil. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. Similar to today’s gasoline vehicles, fuel cell electric cars can have a driving range of more than 300 miles on one tank of hydrogen fuel. Fuel cell cars are very similar to traditional gasoline powered cars. There are also no pollutants emitted from the tailpipe-just water! 4. ![]() Compared to conventional gasoline vehicles, fuel cell vehicles can even reduce carbon dioxide by up to half if the hydrogen is produced by natural gas and by 90%, if the hydrogen is produced by renewable energy, such as wind and solar. Unlike batteries, fuel cells do not run down or need to recharge-as long as there’s a constant source of fuel and oxygen. Fuel cells are a clean way to produce power.įuel cells are similar to batteries in that they produce electricity without combustion or emissions. Because fuel cells can be grid-independent, they’re also an attractive option for critical load functions such as data centers, telecommunications towers, hospitals, emergency response systems, and even military applications for national defense. These range from powering buildings, cars, trucks, to portable electronic devices and backup power systems. Hydrogen and fuel cells can be used in a broad range of applications. Fuel cells can be used to power several applications. ![]()
